To all whom it may concern.-

Be it known that we, ROBERT W. Cox and John ll. ()NTRICH, citizens of the United States, residing in Washington, District of Columbia, have invented a new and useful Improvement in Pocket Check-Punches, of which the following is a specification. I

This invention relates generally. to check punches or perforators, and more particuarly to one so constructed as to be convenicntly carried in the packet.

The object of the invention is to rovide an exceedingly simple andmfiicient orm of pocket check punch, which will not only be useful as a check punch, but can also be utilized as an advertising medium.

With these objects in view, the invention consists essentially of two metallic disks connected together by means of a rivet, the upper disk being adapted to turn upon the lower disk, said upper disk being constructed with means for perforating a check held between the said disk, the lower disk having a perforated bed portion upon which the check is perforated, said lower disk being also provided with means for maintaining the upper disk in its proper position with relation to the lower disk, and also with means for holding the said upper disk steady after it has once been properly adjusted.

The invention consists also in various features of construction and also in the novel manner of combining and utilizing said features, all of which will be fully described hereinafter and pointed out in the claims.

In the drawing forming a part of this specification:Figure 1 is a perspective view of a pocket check punch constructed in accordance with our invention. Fig. 2 is a to plan view of the same. Fig. 3 is a sectiona view on the lines 33 of Fig. 2. Fig. 4 is a plan view of the bottom disk and Fig. 5 is an inverted plan view of the upper disk. Fig. 6 is a detail perspective view showing the perforated bed-plate and fulcrum lip.

In constructing a pocket check punch in accordance with our invention we employ a metal disk A which may be of any suitable material and this is the disk which we designate the lower disk. At diametrically opposite points this disk is provided with slight extensions, the ends of which are curved as shown at A, in order to afford a convenient grip upon the device, it being understood that the said device is held between the thumb and fore-finger of one hand, while the upper disk is'being adjusted with the other hand. The bottom disk A has a central opening A through which passes the pivot post B, said central opening being preferably square in shape, so that when the parts are connected, the pivot or post B become rigid with the bottom disk A, and turning upon this central post or pivot B is the top or upper disk C, the upper end of the post or rivet being headed down to firmly connect all of the parts together. The upper disk C carries the numerals t, and any other characters desired, said characters being preferably stamped or punched into the said upper disk in such a manner as to form punching dies which protrude from the lower face of said upper disk, as most clearly shown at C, in

Figs. 3 and 5.

It will of course be understood that the check to be punched is held between the disks, and the upper disk adjusted so as to bring the proper numeral over the proper place on the check, and then by bringing that portion of the upper disk down upon the check, the proper numeral is punched into or upon the check, and to render this operation complete we provide a perforated bed-plate D which is punched up from the bottom disk as most clearly shown in Figs. 3, 4 and 6, the perforations of said portions being so arranged as to register with the protruding portions of the dies C so as to render a complete perforation of the check possible. It will be understood, however, that it is not absolutely necessary for the bed-portion to be perforated, as it will be sullicient if the upper surface thereof is roughened. The bottom disk A has two transverse lips E and F punched therefrom and turned up at a right angle as shown in Figs. 3 and 6, said lips serving to hold the upper disk C the proper distance away from the lower disk A, and these lips also serve as afulcrum when the check is to be perforated, the disk F being arranged between the center of the plate and the bed-portion D, and furthermore it will be noted that this lip F is provided with two teeth F which are so spaced that they will engage the radial grooves F produced in the lower face of the upper disk, so that when a numeral or other character is brought directly over the bed-pl ate D of the lower oisk, the teeth F will enter the radial grooves F and thereby hold the said upper disk against further pivotal movement, and the check can be then inserted and the edge of the disk ressed down, so as to punch the check. The ip F also serves as a stop against which the ed e of the check can be made to rest.

Tn orderto provide for a perfect impression, we construct the outer or circumferential portion of the 'upper disk C upon a slight inclination as shown at C so that when the disk is pressed down at one point for the purpose of punchin the check, the portions so pressed down will come into arallel relation with the upper face of the edportion D just as the check is to be punched,

and in this manner a complete and perfect perforation or impression is obtained it being understood that the upper disk is made of metal sufficiently elastic or yielding to permit such movement, and then return to its normal osition, the moment the pressure is remove .f The outer edge of the upper disk is Ililllled to facilitate the adjustment of said The operation of the device will be thoroughly understood from the description already iven, and it will be understood that if desire? the advertisement of a bank or other financial institution may be stamped or otherwise arranged upon either one of the disks at the time it is manufactured. It will also be understood that slight changes or variations in the details of construction may be had so long as the essential features of the 40 invention are not departed from.

Having thus fully described our invention,

what we claimas new and desire to secure by having a fulcrum and a roughened surface adjacent thereto, an u per disk rotatable upon the lower disk, an having its circumferential portion inclined, said inclined portion bein provided with punching dies.

3. A c eck and lower dis s pivotally connected, the lower disk having a lip punched therefrom, said lip being provided with teeth, the upper disk having its central portion radially grooved, the teeth of the lip being adapted to engage the radial slots for the purpose of holding the upper disk, said upper and lower disks being rovided with means for punching the check as set-forth.

4. A check unch comprising the upper and lower disks pivotally connected, the lower disk having a bed portion unched therefrom and also two transverse ips, one

punch comprising the upper of said lips being provided with teeth, the upper disk having its central portion radially grooved and its circumferential portion inclined, said circumferential portion carrying the dies, all of said parts being constructed, arranged and ada ted to operate substantially as shown an described.
